Apache2

als Webserver verwenden wir Apache2 mit PHP4, mod_security, mod_deflate und ZendOptimizer

<IfModule mod_security.c>

    # Turn the filtering engine On or Off
    SecFilterEngine On

    # Make sure that URL encoding is valid
    SecFilterCheckURLEncoding On

    # Only allow bytes from this range
    SecFilterForceByteRange 1 255

    # The audit engine works independently and
    # can be turned On of Off on the per-server or

    SecAuditEngine RelevantOnly

    # The name of the audit log file
    SecAuditLog /var/log/apache2/audit_log
